The user creates a gigantic dragon out of water and, by thrusting both hands forward, sends it to attack the opponent. This technique is able to absorb the chakra from an opponent's technique and in turn, use that chakra to grow larger and more powerful. Therefore, the stronger the opponent's technique is, the stronger this technique will get.
This technique is based off of Kisame Hoshikage's Water Release: Great Shark Bullet Technique
